Seth Castillo

Seth started at Coryell about 7 ½ years ago on the company’s residential roofing side, at that time in Amarillo, TX. It was here, Seth was an hourly worker, able to learn all aspects of roofing from the ground up, and today carries the responsibilities of a project supervisor. As Coryell grew and transitioned into a commercial-only roofing company, Seth grew too. He obtained additional specialized training, and with that came title changes within the company. Nevertheless, like his daddy said, “call me anything you want, just don’t call me late for supper.” The Coryell journey has been a welcomed one by Seth. Before Coryell and his current Senior Project Manager position, Seth ran a truck body shop in his hometown of Canyon, Texas, and was a welder for 11 years before that. He also attended Behavioral Psychology at Ashford University. These days, Seth enjoys family time and bass fishing in tournaments or just for fun. He has an amazing wife, Stephanie, a step-son in Florida, a precious daughter, and a crazy little family dog named Chi-Chi. Through all of life’s ups and downs, Seth believes what Gandhi said, “You must be the change you wish to see in the world.”
